My invention relates to two-part rack members of'machines for use in dyeing, bleaching or otherwise wet-processing skein yarn, cotton, wool or any fiber material and has more particular reference to equipment for removably fastening together registering side rails of the upper and lower portions of the two-part rack members.

A purpose of my invention is-to provide a form of fastening between the registering side rails of the upper andlower parts of composite racks of the character indicated that is inexpensive to manufacture and well adapted to efiiciently perform theneeds of service. I

A furtherpurpose is to mount upwardly extending bolt members upon the rails of the lowerportion of a two-part rack to cooperate, with looking levers vertically pivoted upon the rails of the upper portion, the levers] in looking position hooking under downward abutments on the upper ends of the bolts. 1

A further purpose is to lessen the forwardly presented slope of a movable locking member upon the upper portion of a rack of the characterindicated by providing vertical adjustment in a cooperating abutment member uponthe upper end of a bolt member carried by the lower part of the rack and engaged during the locking movement by the sloping portion of the lockingmember.

Further purposeswill appearinthe specification and in the claims.

I have elected to show one form only of my invention selecting a form that is practical and eiiicient in operation and which well illustrates the principles involved.

Describing in illustration and not in limitation and referring to the drawings My invention refers to a detail of a twopart rack for use with machines for treating fibrous material with a liquor that may be for dyeing, bleaching or for any other processing operation. 1

In Figure 1, I show a two-part rack 10 made up of upper and lower members 11 and 12 respectively, the composite rack being part of a dyeing machine 13.

The dyeing machine includes a dye vat l l which may be square or rectangular and con tains dye liquor 15 adapted to be continuously circulated by a. suitable circulating unit 16.

The upper and lower members of the-composite rack are separable and are used as a unit when together and as separate units when apart. The upper member 11 is usually used alternately with each one of two similar lower members 12 of which one only is shown. They are adapted by means of my invention to be interchangeably easily fastenedto the upper member 11.

Each lower member 12 includes transverse poles 17 for receiving skeins of yarn or the like and side rails 18 that are notched at 19to receive the pole ends and that are adapted to register with corresponding 'downwardy presented side rails 20 of the upper member 11. These side rails 20 are not notched.

, In operation one of the lower members 12, loaded with skeins of yarn or the like is in the dye vat presenting its load to the action of the dyeing liquor while the other lower member on a suitable truck 21 is being unloaded from material, as yarn 22, that has been previously operated upon by the liquor inthe mayou '60 Y teriallyreducefthe slope of the wedge; adjustchine and is then reloaded with material not yet treated in the vat.

' I provide the rails of the lower members 12 with upwardly directed metal members that pass throughregistering vertical perforations My fastening includes upwardly directed metal members 23preferably bolt members extending fromthe lower rails Withlower shanks 24 firmly fastened tothe lower rail and an upwardly directed extension adapted to pass through perforations 25 of the upper rail 7 and each presenting a, vertically adjustable abutment 26 inpositioni'to make cooperating engagement with a preferably slightly slopingupwardly'directed surface 28 ofthe hook portion of a-pivoted lock lever 27. i e

Furthermore, with the handfoperated lever there is little or no straining of or injury to the threads on bolt 23, such as might bethe' caseif hook 28 jammed against nut 33 instead of slippinginto position under nut 33.

This might occur if nut 33 became loose and slipped down on to bolt 23.
